CY74FCT2543T, 8-BIT LATCHED TRANSCEIVER

The CY74FCT2543T octal latched transceiver contains two sets of eight D-type latches.

Separate latch enable (LEAB, LEBA) and output enable (OEAB, OEBA) inputs permit each latch set to have independent control of inputting and outputting in either direction of data flow.

For example, for data flow f
